Communications information

Step 2. Client System

Install or upgrade to the latest level of the client software and the TSM API software. Then install the storage agent software.

Install the Client and Upgrade the API

  1. Check that the Tivoli Data Protection client system meets the prerequisites for client software. See the applicable Tivoli Data Protection documentation. Install the client software if it is not already installed on the system, or upgrade the software to the latest level as necessary.
  2. Ensure that the client connects with a server that supports the Managed System for SAN feature. The client options file (dsm.opt) must include the TCP/IP address of the server. For example:
    commmethod tcpip
    tcpserveraddress garden.tucson.tivoli.com
    tcpport 1500
    
  3. Update the API software to the latest level by following the procedure described below.
    Note:Ensure that the Tivoli Data Protection client is already installed.
    1. Download the TSM Version 4.1 for the Windows backup-archive client and the associated BAT file from http://www.tivoli.com/support/storage_mgr/tivolimain.html .
    2. Run the BAT file to unzip the files, and follow the directions to begin the installation procedure.
    3. From the Setup Type window, click Custom.
    4. From the Select Components window, select Client Files and click Change.
    5. Select API Client Runtime Files and deselect the other components.
    6. Ensure that you specify as the installation directory for the API the same directory as that in which the existing API resides.
  4. Manually set the option in the client options file (dsm.opt) to enable the LAN-free data transfer. You cannot set this option through the graphical user interface (GUI). Add the following line to the dsm.opt file:
    enablelanfree yes
    
    The enablelanfree option specifies whether you want the client to use SAN-attached devices during backup, restore, archive and retrieve processing, if the path to the SAN devices is available.

    For information about the dsm.opt file, refer to the Tivoli Storage Manager Installing the Clients.

Install and Configure the Storage Agent

On the same system as the client, install the storage agent.

  1. Gather the following information:
  2. Insert the Managed System for SAN CD-ROM in the drive of the client system. Follow instructions on the screen to install the storage agent. The results of the installation are:
  3. Ensure that a device configuration file exists and that the matching DEVCONFIG option is in the dsmsta.opt file. For example, for a device configuration file named devconfig located c:\program files\tivoli\tsm\storageagent, edit the dsmsta.opt file and enter the following line:
    DEVCONFIG devconfig
    
  4. Use the information that you collected in step 1 to issue the DSMSTA SETSTORAGESERVER command. For example:
    dsmsta setstorageserver myname=iris mypassword=jonquil
     servername=garden serverpassword=botanical
     hladdress=garden.tucson.tivoli.com lladdress=1500
    
    See Set Installation Data for the Storage Agent: DSMSTA SETSTORAGESERVER for the details on the command parameters.

    The command generates the following lines in the device configuration file for the storage agent:

    +--------------------------------------------------------------------------------+
    |SET STANAME iris                                                                |
    |SET STAPASSWORD xxxxxxx                                                         |
    |DEFINE SERVER garden serverpassword=xxxxxxxxxxx                                 |
    | HLADDRESS=garden.tucson.tivoli.com LLADDRESS=1500                              |
    |                                                                                |
    +--------------------------------------------------------------------------------+

    The passwords (shown here as xxxxxxxx) are encrypted in the file.

    The command also generates the following line in the dsmsta.opt file:

    +--------------------------------------------------------------------------------+
    |SERVERNAME garden                                                               |
    +--------------------------------------------------------------------------------+
    See The Storage Agent Options File and The Device Configuration File for the Storage Agent for details on these files.

Step 3. Server

The following is an overview of the steps that you need to do on the TSM server. For details, see Administrator's Guide. On the server, you will do the following:

  1. Configure the SAN drives. This involves the following steps:
    1. Define a shared SCSI library
    2. Define drives that are associated with the library
    3. Define the device class
    4. Define the storage pool
  2. For each client for which you want to enable SAN data transfer, define that client's storage agent as if it was a server. You must use the same name and password that you set for the storage agent when you installed it on the client system. For example:
    define server iris serverpassword=jonquil
     hladdress=sanclient.tucson.tivoli.com lladdress=1500
    
  3. Modify policy for the client so that the storage agent acting on behalf of the client uses the drives on the SAN. The client must use a management class that has copy groups with a destination storage pool that is associated with the library on the SAN for which you have mapped drives for the client. See Administrator's Guide for details on changing policy for clients that can use SAN drives. For example, do the following:
    1. Create a policy domain for clients that will use the SAN devices for direct data transfer.
    2. Create a policy set in that domain.
    3. In the default management class for that policy set, modify the copy groups: Set the destination storage pool to the storage pool associated with the SAN drives that you configured and mapped for the client.
      Note:If you decide not to use the default management class for the SAN drives, you will need to create a new management class. Clients that want to use the SAN drives then need to update the include-exclude list to specify the new management class. See Tivoli Storage Manager Installing the Clients for details on the include-exclude list.
    4. Activate the policy set.
    5. Register or update the clients so that they are in the new policy domain.

See Administrator's Reference for details on the commands.

To review the expected results of the steps that you have just completed, see Figure 3.
